SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 294,774, dated March11, 1884,

' Application filed January 12, 188-1. (No model.) v

To a/ZZ whom it may concern.-

Be it known that I, FREDERICK EBERLEIN, a citizen of the United States,residing at Ghicago, in the county of Cook and State of Illinois, haveinvented certain new and useful ImprovementsinWindow-Fasteners, of whichthe following is a specification.

This invention relates to an improvement in window-fasteners; and itconsists in certain peculiarities of construction and arrangement of thesame, substantially as will be hereinafter more fully set forth andclaimed.

In order to enable others skilled in the art to avail themselves of thebenefits of my invention, I will now proceed to describe itsconstruction and arrangements, referring to the accompanying drawings,in which- Figure 1 is a perspective view of my inven- Figs. 2 and 3 aredetails of the same, and Figs. 4 and 5 are modifications designed foruse 011 windows having a central division-bar.

A represents a square or angular bar journaled in small castings a a ateach end, secured to the top of the lower sash. Upon the center of thisbar or rod is placed a handle, B, preferably bent, as in Figs. 1 and 2,and formed with a small lug or nose, b, on its rear side, which bearsupon the sash and acts as a stop to prevent the bar from turning toofar.

Each end of the rod A is provided with an arm, 0, hook-shaped at itsouter end, and a spring, 0, is coiled around said rod, and, bearingagainst the window and the arm 0, holds the latter always in a lockedposition.

The upper sash is provided with a series of stops, (1 (1, arranged inpairs, as shown, the lower of which, (I, is formed with an underbeveledend, as in Fig. 3, for engagement with the hook-arm 0. Any number ofpairs of these stops are placed upon the upper sash at desiredintervals, and as their rear ends are beveled, as at d (2 it is evidentthat whenthe sash are raised or lowered the arms 0 C will ride easily upon the stop, and the springs c 0 cause them to drop into the spacebetween them, and thereby lock the two sash securely together, whilepressure upon the handle B will at once throw them out of suchengagement and release the sash. IVhen so locked, any upward pressureagainst the lower sash acts against the end of the upper stop, 01, and

any downward pressure against the beveled end of the stop (1, and thisbevel, with the hook upon the arm 0, prevents such pressure from causingthe arm to be thrown orslid back, as might otherwise be done. The lug 1)prevents the springs from throwing the arms 0 against the sash andinjuring the paint.

WVhile this device may be applied to any window, a slight modification,as seen in Figs. 4 and 5, may be sometimes used upon sash having avertical division-bar in the center. This modification consists incasting the handle B and arm 0 in one piece, with lugs or journals toreplace the bar or rod A, either cast with or passed through thecasting. The spring 0 and stops (2 03 are'used in precisely the samemanner already described, but placed upon the central division-bar ofthe upper sash, .and the casting B O secured at the center of the lowerone, as will be readily understood.

Itis evident that the rodAmay be supported and braced by placingcastings a a in the cen- 0 upon the lower sash, in combination with thestops (1 d, beveled upon one end, and one of them under-beveled,substantially as shown, and for the purpose set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

FREDERICK EBERLEIN.
